APPARATUS FOR CARBONATING LIQUIDS.

Application filed October 6, 1899. berial No. 732,799. (No model.

To aZZ whom it may concern:

Be it known that I, ALFRED WALL, brewer, a subject of the Queen of GreatBritain and Ireland, and a resident of Lezayre road, Ramsey, Isle ofMan, England, have invented a certain new and useful Apparatus forCarbonat-ing Liquids, of which the following is a specification.

The object of my invention is to provide an improved apparatus forcarbonating liquids.

The process of carbonating liquids by carbonic-acid gas has been doneheretofore before bottling, and by means of my invention this processcan be accomplished after bottling.

Referring to the drawings which form a part of this specification,Figure 1 represents an elevation of the apparatus, shown partly insection. Fig. 2 is an enlarged section of an improved self-actingstopper forming part of this invention, Fig. 3 being an outside view ofthe same; and Fig. 4 is an enlarged section of the tube and valve forinserting in the stopper when carbonatingin the manner hereinafterdescribed.

In the several views, A is the bottle the liquid in which is required tobe carbonated; B, the improved self-acting stopper, which is fitted tothe neck 0 of the bottle.

D is the tube inserted in the end of the stopper B, having arubber-cork-connecting cone E and loose brass washer F. The said smalltube has a miter valve end G and passes through the screwedvalve-seating H and is kept gas-tight by the stuffing-box I, formed bythe nut J. This screwed valve-seating H is screwed to the inlet-piece Kby means of the nut L. The aforesaid small tube D is hollow for agreater part of its length, as shown at M, and is provided with asmallhole N, leading from this hollow portion to the outer surface of thetube. This small hole forms the automatic inlet, to be hereinafterdescribed. The coil-spring 0 serves to keep the tube D pressed upward,with the miter end resting against the seating H. The gas is admittedthrough the inlet P from the pressure-reservoir or gas-supply into thechamber of the inlet-piece K, but cannot escape further on account ofthe small tube D being close against the seating H by the action of thecoil-spring O.

The process of carbonating takes place in the following manner: Thebottle already filled with the liquid is stoppered by the improvedstopper aforesaid. This stopper is made in such a way, as shown by thedetail section in Fig. 2, that the gas .or any other material to beadmitted into the bottle can be so admitted through said stopper, butcan not escape back again. To do this, I form a hole B through thestopper lengthwise and nearly along its length, and at the innertermination of said hole I form another at right angles, extending fromthe center to the side, as shown at B This hole is covered by anindia-rubber tube or band B which envelope the outer surface of saidstopper. The bot tle and stopper are placed in an inverted position in asuitable frame or stand R, the upper portion of which has a stem Q,terminating in a flange S at its lower end, the upper end sliding in asocket T, containing a spiral spring Uto keep said stem bearing downupon the base of the bottle. The sliding socket has an eye at its upperend and in its turn slides up and down in the frame and is con trolledby the lever V. When the bottle is in position, the lever V is raisedand puts a pressure on the bottle against the upward pressure of thespring 0 and so depresses the small tube D, forcing it downward till theside hole N is exposed to the chamber of the inlet-piece K, and the gasrushes through the smalltube D and the improved stopper B into thebottle. When the liquid has been sufficiently carbonated, the handle ofthe'leverV is pulled down, thereby releasing the pressure on the bottle,and the india-rubber ring B on the stopper B prevents any escape of gasfrom the bottle, and at the same time the spring 0 forces the miter endof the small tube D against its seating and shuts off communication fromthe gas-inlet P through the small hole N, and this lower valve is thusautomatically closed and the bottle can be removed.

Having now described my invention, what I claim as new, and desire tosecure by Letters Patent, is

In a fluid-carbonating apparatus the com bination of a frame, areciprocating resilient bottle-carrying stem carried by the frame, aconical tubular cork for the bottle having a lateral inlet and providedwith a flexible band surrounding the sides of said cork and lateral heldand filled by inserting the tubeand cone inlet, a, spring-retractedreciprocating tube within the bottle-neck. 1o exteriorly coned at itsouter end and hav- In Witness whereof I have hereunto set my ing anelastic cone-washer adjacent thereto hand in presence of two witnesses.adapted to enter said tubular cork, a valve ALFRED WALL.
